Although the human eye’s complexity is extensive, it is unable to handle time prolonged computer screen viewing, as the eyes are most comfortable switching between various focal distances and light complexities. Chris’ eyes will be under extreme strain due to her age and slowly degrading eye functionality, as well as the constant use of a digital screen. The pressure on the eye from an iPad screen is due to the screens fixated distance, which is not encouraging the activity of the eye. Two sets of muscles work in synergy to establish an adequate focus on objects, the first set converges the eyes to the same point, whereas the other flexion allows the lenses in each eye to focus the light produced by the computer screen onto the eye. As looking

It is likely for Chris to develop Myopia, a form of shortsightedness, where the light from a distant object is focused in front of the retina rather than behind, which can explain why she has clear near vision but blurred distant vision. Glasses and contact lenses are most common in treating mild myopia symptoms, which refocus light rays on the retina to accommodate for the shape of the eye. If Chris’ case is diagnosed as extensive, she could be recommended to have LASIK refractive surgery, where surgeons can reshape the cornea and front surface of the eye, which would in turn dramatically improve her focusing ability between near and far …show more content…
Tim’s vision during the day would be impaired due to this red-green colour blindness of cone cells (which are less sensitive to light), and he may incorrectly interpret colours. As an example, traffic lights may be hard to read due to how similar the “tones” will appear to Tim, and he would need to distinguish between the “lit” lights. Rods work in low light conditions and can assist with night vision, but only in black, grey and white. Tim’s vision during the night would not be impaired due to this factor, having seen that colour vision deficient individuals have better night vision than a regular person due to their rod: cone ratio being higher in the retina. Colour vision deficiency is known as a genetic condition and has statistically been shown to affect more males than females. However, some colour blindness can also be a result of a genetic dysfunction (mutation) during growth.
Chronic kidney disease, also known as chronic renal disease or chronic kidney failure is the progressive deterioration of kidney function over an extensive period and ultimately leads to permanent kidney failure after some years. Chronic kidney disease is often left undiagnosed until the failure is forthcoming and function is around 25%. The kidneys undertake the complicated method of filtration within our bodies, and as failure
